Mice oxygen consumption rate - Essay Example

Author Tutor Course Date #1 Define endothermic species Endothermic species refers to animals that must generate their own heat so as to sustain their body temperature. Endothermic species can sustain their body temperature with that of the environment. Some of the characteristics of endothermic animals include the capability to generate heat within their bodies themselves, and capability to sustain body temperature by controlling their metabolic rates such as enhancing their metabolic rates in the event that the atmospheric temperature starts to reduce…

Warm-blooded animals maintain thermal homeostasis via internal metabolic processes; hence, endotherms can remain active over a broad range of ambient temperature (Stanier 79). # 2 Define metabolic rate Metabolic rate refers to the amount of energy utilized in a set period. Metabolic rate represents the pace at which energy can be utilized by an organism and encompasses the integration of all catabolic energy transformations in the body, as well as the intensity and speed of life itself. The metabolic rate may be enhanced by several processes of considerable ecological significance including tissue synthesis, food processing, and physical activity. The metabolic rate remains closely related to the rate of ATP production measured by cellular respiration (oxygen consumption or carbon dioxide production. Metabolism represents the set of life-sustaining chemical transformations in the cells of living organisms. Metabolism also refers to all chemical reactions that manifest within living organisms including transport of substances (Cannon and Nedergaard 242). # 3 Factors that affect metabolic rate The metabolic rates can be essentially determined by relatively few factors, namely: temperature, phylogenetic affinities, and mass. The body temperature possesses pervasive impacts on biological processes via the influence of temperature on the activity of metabolically significant enzymes. The metabolic rates double or triple in the event that body temperature increases by 10°C. The absolute levels of metabolism that the temperature levels establish may be subject to acclamatory or evolutionary changes through the alteration of enzyme structure or composition. In endotherms, the impacts of the core thermal dependence may be surpassed by the physiological regulation of body temperature, which is energetically expensive ((Navas and Jose? 13). One of the primary factors impacting on metabolic rate is boy size or body mass. The metabolic rate interspecifically relates with body mass. Individuals with greater body weight manifest a higher resting metabolism relative to smaller individual since their body would have to work “harder” to support and sustain the extra weight. This theory stipulates that, endothermic animals must metabolically generate enough body heat to balance the heat lost via their body surface if they were to maintain a constant body temperature. Phylogeny: The metabolic level differs among taxa, whereby the phylogenetic history of an animal determines the rate of energy expenditure (Navas and Jose? 15). Moreover, men usually possess less body fat and more muscles relative to women of the same weight and age, which leads to burning of more calories. As people get older, the size of the muscle tends to reduce, which in turn slows down calories burning. # 4 How metabolic rate is dependent on the ambient external temperature The temperature of an animal relies on the amount of heat contained within the animal’s body. Animals can absorb or lose heat from or to the environment via several processes such as convection, conduction, radiation, and evaporation. The amount of heat transferred into or out of an animal hinges on the surface area, heat

(Herzberg, 1934). Over the past twenty five years significant increase in data regarding singlet oxygen has led to the recognition of its importance in organic chemistry, biochemistry and medicine. Singlet oxygen is an extremely reactive, nonradical, electrophilic molecule.

Of Mice and Men
Of Mice and Men by John Steinbeck is believed to be one of the classic novels written in the twentieth century. The major theme of this novel is revolving around the bitter experiences suffered by two workers; George Milton and Lennie Small, during the Great Depression period.

Mice urine and feces are poisonous and can be a factor of food poisoning among other probable damages, such as chewing clothes, damaged wires in buildings and even documents. Single female mice can reproduce around sixty offspring during its lifespan. With the gestation period of a mice being twenty-one days, they are capable of multiplying fast if no action is taken immediately against this.

This therefore, gives a clear impression that the ways of consumerism differs from one individual to the next. There are various factors that influence the way in which an individual controls consumerism. In the whole world, every nation is different especially because of the administration.

Since oxygen is a gas, the pressure at which it is available is almost as important as its very presence in a given situation.
Living cells need oxygen all the time but have no mechanism to store it (Treacher, and Leach, 1998). Most cells, especially those of the human brain, which controls life processes, cannot survive for more than a few minutes without a continuous supply of oxygen at the right pressure.

It also provided opportunities for students to perform accurately the procedures in the use of LaMotte Dissolved Oxygen kit, titrations and balance and allowed them to compare the oxygen consumption among organisms. The laboratory activity is practically experimental, were experimental and control group designs have been applied.

The generated energy is used to carry out important functions including growth and movement in animals. Life of every structural and functional unit of any life form depends upon the availability and utilization of oxygen.

The major part of the solid substances of a living organism is made up of organic material. However, these organic compounds are not sufficient for the human body. In order to live, a living organism has to perform many chemical reactions. These

Shopping centers and women played very crucial roles in the creation of the identity of the modern consumer (Hamilton 571). The following paper considers the impacts of people whose consuming behavior determines and shapes their desires,
